Azure provides at-scale tags management through Azure Policy
Published date: 19 September, 2019
Azure Policy helps to enforce organization standards for tagging requirements.
It can automatically apply, inherit, replace or delete tags across the entire organization to enforce standards.
For example, Policy can inherit the tags from the resource group to its resources, or replace Env: Prod tag with Environment: Production for consistent tagging convention.
Azure Policy also supports remediating existing resources to bring them to 100% compliance.
Sample definitions are already available in your Azure environment today.
